I have not seen anyone try this out.
I have an idea to create a podcasting network, which includes several podcasts by several podcasters, but under one network name, and many podcast show names. If that makes any since.
ie. MTV( the network) cribs, pimp my ride( the individual shows) I would like to do this with my podcasts.
So that the network is one, but the shows and podcsters are many , but can see perhaps some info about others. Im not sure how this would work.

I think there have been a number of commercial ventures to do this. Most notably: http://www.podtech.net/home/
A good essay discussing this is at http://scobleizer.com/2006/11/10/competitors-of-podtech-that-i-love-er-going-to-the-content-mall/
